Abstract

A kneading and modeling compound or clay and the use of such compound which is constituted of binding agents, plasticizers and/or solvents, as well as fillers. The fillers include aluminum hydroxide. The compound may also include pigments and other additives.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. In a kneading and modeling compound, including binding agents, plasticizers, solvents, fillers, pigments and other additives; the improvement comprising in that said filler includes at least about 5% aluminum hydroxide. 
     
     
       2. A compound as claimed in claim 1, comprising 50 to 70% binding agents,   10 to 40% plasticizers and solvents,   5 to 40% aluminum hydroxide, and   0 to 10% pigments and other additives and fillers.   
     
     
       3. A compound as claimed in claim 1 or 2, said binding agent comprising microbead-paste PVC. 
     
     
       4. A compound as claimed in claim 1 or 2, said binding agent comprising at least about 0.5% cellulose ether. 
     
     
       5. A compound as claimed in claim 1 or 2, said binding agent comprising at least about 10% ceresin wax. 
     
     
       6. A compound as claimed in claim 1, comprising 50 to 70% PVC,   4 to 10% calcium stearate,   5 to 10% aluminum hydroxide,   20 to 30% di-2-ethyl hexylphthalate,   0.5 to 2% octyl fatty acid ester, and   0 to 2% pigment.   
     
     
       7. A compound as claimed in claim 1, comprising 0.5 to 2% cellulose ether,   15 to 50% water,   50 to 85% aluminum hydroxide, and   0.1 to 1% preservative medium.   
     
     
       8. A compound as claimed in claim 1, comprising 10 to 25% ceresin wax,   10 to 40% paraffin oil,   50 to 80% aluminum hydroxide, and   0.1 to 1% pigment.   
     
     
       9. A compound as cliamed in claim 1, at least 95% of said filler having a grain size of less than 5 μm. 
     
     
       10. The use of a compound for kneading and modeling comprising a high-molecular binding agent selected from the group consisting of polyvinyl chloride, cellulose ether and ceresin wax; plasticizers and solvents and other additives; and a filler containing at least about 5% aluminum hydroxide. 
     
     
       11. The use of a compound as claimed in claim 10, comprising 50% to 70% high-molecular binding agent,   10% to 40% plasticizer and solvent,   5% to 40% aluminum hydroxide, and   0% to 10% pigment, other additives and fillers.   
     
     
       12. The use of a compound as claimed in claim 10, comprising 50 to 70% microbead-paste PVC,   4 to 10% calcium stearate,   5 to 10% aluminum hydroxide,   20 to 30% di-2-ethyl hexylphthalate,   0.5 to 2% octyl fatty acid ester, and   0 to 2% pigment.   
     
     
       13. The use of a compound as claimed in claim 10, comprising 0.5 to 2% cellulose ether,   15 to 50% water,   50 to 85% aluminum hydroxide, and   0.1 to 1% preservation medium.   
     
     
       14. The use of a compound as claimed in claim 10, comprising 10 to 25% ceresin wax,   10 to 40% paraffin oil,   50 to 80% aluminum hydroxide, and   0.1 to 1% pigment.   
     
     
       15. The use of a compound as claimed in claim 10 for the production of models, model molds, plastics, reliefs and various plastic objects and representations. 
     
     
       16. The use of a compound as claimed in claim 15 wherein said compound is hardened at an elevated temperature. 
     
     
       17. The use of a compound as claimed in claim 15, wherein said compound is hardened through air-drying at approximately room temperature. 
     
     
       18. The use of a compound as claimed in claim 15, wherein said compound is maintained permanently plastic and constantly remoldable. 
     
     
       19. The use of a compound as claimed in claim 10, at least 95% of the filler having a grain size of less than 5 μm.
